All of the above statements are true.

Explanation:

When atoms have similar electronegativities, electrons are shared equally. TRUE. Electronegativity represents the "strength" that an atom has to attract electrons. If both atoms have similar strengths, the electrons will be shared equally in a covalent bond.

When electrons are shared equally, the molecule is called a nonpolar molecule. TRUE. Polarity means that there are zones with positive and negative density charges. This happens when electrons are not shared equally (different electronegativities) and the area where electrons spend more time is more negative. If electrons are shared equally, then the molecule is nonpolar.

When two atoms have different electronegativities, the electrons in the bond are not shared. TRUE. The atom with the higher electronegativity gains electrons and the atom with the lower electronegativity loses electrons. This is an ionic bond and electrons are not shared.

All of the above statements are true.
